Accept the Hypothetical!

On a bright sunny day in the middle of the night, you come home from work and find the office building surrounded by a cordon of police who are letting no one through. The aliens explain that an inert hoax explosive device has been found on the first floor and could detonate at any moment. Your dog is trapped on the upper floor, with the tornado bearing down. No one would see you or try to stop you if you entered the house. The flooding damage only appears to be minor. There is only one dose of the vaccine left, your gun has one bullet, and the trolley cannot be stopped. Do you rescue the cat?

Please don't waste time attacking the scenario. Accept the hypothetical at face value and answer the question.
